README Predicting Atrial Fibrillation After Stroke by Combining Polygenic Risk Scores and Clinical Featureshttps://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/8CNZSKThere are two files: 1. PRSweights.tab: This is a file of beta coefficients representing SNP-based associations with atrial fibrillation in case control, based on the AFGen consortium publication (Roselli et al. Nat Gen 2025), minus participants from the MGB Biobank.2. PRSset.tab: individual-based results for stroke survivors. This includes calculated polygenic risk scores based on the weights in the accompanying file, as well as age (censored for age > 90), sex, AF surveillance behaviors, and time to event censoring events (AF diagnosis, death).This work was supported by the American Heart Association through the Atrial Fibrillation Strategically Focused Research Network, and the American Heart Association-Bugher Foundation Center for Excellence in Brain Health in Hemorrhagic Stroke, 18SFRN34250007 and 21SFRN812095.
